Title: Optical multiplexer
Inventor: MORI TATSUO
IPC: H04J14/08
Filed: 1992-02-25
Abstract: PURPOSE:To obtain an optical signal whose intensity is twofold of an output level of a light source unit by delaying one of divided optical signals by 1/2 of a modulating period, and thereafter, synthesizing both the optical signals by a polarization synthesizer. CONSTITUTION:An output signal light of a light source unit 18 is inputted to an optical modulator 11 through an optical fiber 17. In the optical modulator 11, its output signal light is subjected to amplitude modulation by a pulsative electric signal of 50% duty supplied from a transmitter 19, and the modulated optical signal is separated into two waves and outputted to optical fibers 14, 15, respectively. In the optical fiber 15 which one of these separated optical signals passes through, an optical delaying device 13 having a delay of a period which becomes 1/2 of a modulating period of the optical modulator 11 is provided. Subsequently, the optical signals from the optical fiber 14 and the optical delaying device 13 are synthesized by a polarization synthesizer 12 being a polarizer. In this case, an output signal of the optical multiplexer is an optical signal modulated by a modulating signal frequency from the transmitter 19, but in the case a frequency of a transmission signal is smaller than a modulation frequency, there is no influence exerted on the signal transmission.

Title: Scanning electron microscope
Inventor: MORIWAKI HIRONOBU
IPC: H01J37/22
Filed: 1987-02-20
Abstract: PURPOSE:To make it possible to always observe an image with optimum quality of screen by detecting a ratio of signal to noise in an information signal obtained owing to radiation of electron beams on a sample and increasing/ reducing a current of electron beams which are radiated on the sample depending on this ratio so that the image is displayed based on the signal with a desired S/N. CONSTITUTION:An information signal obtained from a sample 6 due to radiation of electron beams is detected by a detection means 7. A difference signal S (signal intensity) between the maximum and the minimum of a signal is obtained in a difference signal detecting circuit 14 while the electron beams are scanned on the sample 6, and also a difference signal N (noise intensity) between the maximum and the minimum of a signal is obtained there while the electron beams stay on the sample 6. In succession, a difference signal of S to N is determined and its signal is compared with a referential value so that a current of electron beams radiated on the sample 6 is increased/decreased depending on the compared results. Hence, an image with optimum quality of screen can be displayed.

Title: Drive circuit for motor
Inventor: MIZUMOTO MASAO
IPC: H02P3/12
Filed: 1999-02-16
Abstract: PROBLEM TO BE SOLVED: To prevent breakdown of source-side transistors, when a motor is braked. SOLUTION: This motor is constituted such that when a brushless motor in forward rotation course is made to rotate in the reverse direction, source-side and sink-side transistors for causing a negatively directed drive current for flowing are turned on and off periodically on the basis of the oscillation frequency of an oscillator 13, when the terminal-to-terminal voltage of a current detecting resistor 10 is in a range higher than a reference voltage Vref, and the motor is always turned on, when the terminal-to-terminal voltage of the detecting resistor 10 is lowered down to a value lower than the reference voltage Vref. Consequently, it becomes possible to prevent the breakdown of the source- side transistors to be used due to a large current, when the motor is rotated in the reverse direction.

Title: Extensional lock device of stay damper
Inventor: HIROYAMA KOUJI
IPC: F16F9/00
Filed: 1981-03-16
Abstract: PURPOSE:To prevent a sudden falling of a back door by detecting a lowering of charged gas pressure to automatically make engaging means effective at an extensional position of a piston rod. CONSTITUTION:A piston rod 2 is always urged to an extensional side by charged gas pressure acting upon a pressure receiving surface of a piston, so that when a back door is opened, the piston rod 2 is extended to a full admission position and the back door is supported in a full admission state by charged gas pressure. When the charged gas pressure is lowered below a regular value due to a gas leak and so onm a spring member 11 is extended to push a back-up ring 10 into a cylinder 1. Such movement of the back-up ring 10 forces an engaging portion 13 to be contracted into the cylinder 1, and a bottomed cylindrical cover 6 is kept from moving by the engaging portion 13 so that sliding of the piston rod 2 is locked, thereby to prevent a falling of the back door.

Title: Buffer type gas-blast circuit breaker
Inventor: NAKANO TOSHIYUKI
IPC: H01H33/91
Filed: 1990-02-21
Abstract: PURPOSE:To restrain to the minimum deterioration of dielectric strength and breaking performance at the time of exposure to an arc by setting each average particle diameter of two grades of components of aluminum nitride powder constituting a nozzle. CONSTITUTION:The diameter of a tetrafluoroethylene particle 1 in a particulate constitution inside a nozzle of a buffer type gas circuit breaker is generally 10 to 100mum. Spaces among the tetrafluoroethylene particles are filled with aluminum nitride particles 2 having an average particle diameter of 0.5mum and aluminum nitride particles 3 having an average particle diameter of 3mum. A mode of particle diameter distribution of filled aluminum nitride particles consists of a component having about 0.5mum and a component having an average particle diameter of about 3mum. Upon irradiation of arc energy 4 to the nozzle, most of arc energy radiated to the nozzle is reflected due to a remarkable high light reflection coefficient of the aluminum nitride particle, to become reflected light 5 which does not intrude inside the nozzle. Although a little of arc energy 6 intrudes inside the nozzle, it can be soon diffused because of a remarkably high thermal conductivity of the aluminum nitride so that heat cannot be concentrated on a local portion.

Title: Centrifugal flywheel
Inventor: OKUMURA YASUNARI
IPC: F16F15/31
Filed: 1980-03-25
Abstract: PURPOSE:To reduce the starting load on a power unit, by setting slide bars on the external circumference of an inner wheel and shifting the position of weights of the bars by virtue of springs and centrifugal force. CONSTITUTION:Slide bars 2 are radially planted on the external circumference of an inner wheel 1, each bar 2 being attached with a weight 3 and spring 4 in this order at the tip, and fixed to an outer wheel 5 to compose a flywheel. This can reduce the starting load on a power unit, because the weights 3 are shifted toward the inner wheel 1 at the time of starting or low revolution, while at the time of high revolution, the springs 4 are contracted by the weights 3 due to the centrifugal force, the weights 3 being shifted outward, to play the substantial role of flywheel.
